  1. 11. Translational PET imaging of inflammation

    Författare :Emmi Puuvuori; Olof Eriksson; Tove Grönroos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; Nuclear Medicine; Inflammation; Translational Medicine;

    Sammanfattning : Inflammation is our body’s sophisticated defense mechanism against invading pathogens, traumas, and tumors. Repeatable and non-invasive monitoring of inflammation process would open opportunities to improve our knowledge of several diseases and enable assessment of personalized treatments. LÄS MER

  3. 12. Cancer imaging and image analysis methods in whole-body MRI and PET/MRI

    Författare :Therese Sjöholm; Joel Kullberg; Filip Malmberg; Robin Strand; Håkan Ahlström; Einar Heiberg Brandt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; diffusion weighted imaging; positron emission tomography; whole-body imaging; normal atlas; CAR T-cell therapy; lymphoma; medical image analysis; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Diagnostic medical imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) can provide structural and functional assessments of the whole body. This has great value for potentially systemic diseases such as cancer. LÄS MER

  4. 13. DIXI – a Hybrid Pixel Detector for X-ray Imaging

    Författare :Fredrik Edling; Richard Brenner; Leif Gustafsson; Camilla Rönnqvist; Peter Fischer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; hybrid pixel detector; photon-counting; X-ray; imaging; simulation; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER

  5. 14. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

    Författare :Benedikt J. Daurer; Filipe Maia; Tomas Ekeberg; Janos Hajdu; Richard Neutze; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray lasers; coherent diffractive imaging; algorithms; lensless imaging; flash diffractive imaging; flash X-ray imaging; aerosol injection; FEL; XFEL; CXI; CDI; FXI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. LÄS MER

  7. 15. Application of the Seismic Reflection Method in Mineral Exploration and Crustal Imaging : Contributions to Hardrock Seismic Imaging

    Författare :Omid Ahmadi; Christopher Juhlin; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; Hardrock; Mineral exploration; Crustal imaging; Interpretation; Modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The seismic reflection method has been used extensively in mineral exploration and for imaging crustal structures within hardrock environments. In this research the seismic reflection method has been used and studied to address problems associated with hardrock settings. LÄS MER
